The physics groups helps with fall fest. Alex Henderson stirs up some frosty liquid nitrogen ice cream.
The Astronomy class celebrated the Fall Equinox on Sept. 22, 2010. On their cake is a sky map showing the ecliptic and celestial equator. The Sun is at a RA of 12 hours and dec. of 0 degrees - the mark of the Fall Equinox. Equinox means "equal night" (and day). That occurrence (12 hours of day and 12 of night) for Oklahoma City actually occurs in 2010 on Sept. 27. This semester's Astronomy class heads to Costa Rica in January (hence the relatively small class) to finish the last third of the course at QERC, SNU's "southern campus."
The physics class in 2010 measures the rocket thrust as a function of time as a class demo.
More smoke.
The G Physics class went out to observe the impulse momentum relationship. Here, a rocket engine is attached to a cart and sent down the ramp.
The engine is attached to a force probe that transmit data wirelessly to the laptop.
The cart came in at about 4.4 meters/second, as measure by the motion detector. The spring didn't quite stop the cart as planned. Check out the movie in the next graphic.
The change in momentum (during the first three seconds) from the engine was 14 kgm/s. The impulse (over the same time period) was 13.75 Ns. Not bad!
From beginning to end.
Another day's work done.
